Be it known that I, JEREMIAH C. SINOLAIR, of Toledo, county of Lucas,and `Itate of Ohio, have invented certain new and useful Imchine, andhas for its'object to simplify thel construction, cheapen themanufacture, and render the operation easier than heretofore bydispensingr with the necessity of manually operating certain parts. f

The invention consists in the partsand combinations of parts hereinafterdescribed and pointed out in the claims. f

In the drawings-Figure 1 yisa plan view of a sectional detail viewshowing the type bars and the connection of the key levers therewith.Fig. 4 is a front elevation of a portion;

of the carriage and carriage support. Fig."5 is a transverse verticalsection on lines -x Fig. 1.

employed for returning the carriage, and also the mechanism for feedingthe ribbon. Fig. 7 isa transverse section through the frame of themachine on lines y-y Fig. l showinga modified form of mechanism forreturning the carriage, this mechanism being located at the end oppositeto that shown in Fig. 6. Fig. Sis an edge view of the mechanism on thetop plate shown in Fig. 7. Fig. 9 is'an end v iew of the mechanism shownin Fig. 7 looking directly attheend of the machine. Fig. 10, is a detailview-of the spool shaft and spool, showing the means employed forholding the spool in adjustment. Fig. 1l is a detail view of one of thepawls. Fig. 12 is a plan view of the cleaning brush and operating lever.Fig. 13 is aside view of the same.

The frame of the machine comprises base plate 1, top plate 2, rear endplate 3, curved Fig. 2 is'an end ele- Fig. 6 is an end View of thecarriage, and carriage support illustrating the means' snainrmasg.Nomaden front plate 4 and frontend plate 5. Formed integral with the topplate at each end are two rectangular projections 6, into which are jOurnaledscrew-threaded shafts 7 upon which ismounted M'a carriagesupport comprising a front bar 8, end bars 9 and a rear rod 10.Journaled in end bars 9 is a screw shaft 11 extending the entire lengthof the Vcarriage support, and provided at'one end with a disk 12 havingfour projecting pins 13 with which the hook of 'a bar 14 engages torevolve the same when the bar is'pulled downward by a key lever 15fulcrumed at 15v and normally raised at the outer end to excrt'adownward pull upon bar 14 by reason of a spring 16 secured at the baseot' the machine, and pressing against the under side of the lever. Thebar-14 is normally held in engagement with pin 13, by means of a spring14. See Fig. 2.

It will be seen from the foregoing that lwhen the outer end of lever 15is depressed, v bar "14 is raised, and the hook of the bar ywill engagea pin- 13 when upon releasing the spacing key, the spring will raise thefront end of the lever, and cause the rear end to be depressed, therebyrevolving the wheel ya one-fourth turn which gives to the carriage theproper movement to space the letters, anyv further spacing being givenby merely depressing the spacing key, as many times as necessary toadvance the carriage the desired distance. I have provided however, forau vautomatic control of thelever 15 for spacing between `theletters-which consists in extending aV barY 17 at right angles to lever15 and connected with the end, so that when any of the key levers areoperated to print a character, it depresses the outer end of the lever15 and when the key is released the same operation takes place and thescrew yshaft is given one-fourth turn.

The carriage comprises a rectangular frame v IOO to the carriage ineither direction, according to the direction of rotation of the screwshaft, the opposite or front side of the carriage being provided withtraveler wheels 22 which roll upon bar S of the carriage support frame.Bar 1.4 being employed to revolve the screw shaft to advance thecarriage when writing, I will now describe the means employed to revolvethe screw shaft in an opposite direction to return the carriage.

Referring to Figs. l, 5, and 6,23 designates a gear journaled upon theright hand side of the machine within the frame, and meshes with a smallpinion 24 secured upon the end of the screw shaft ll,there being abarrel 23 upon the gear, to which a strap 25 is secured, the strappassing below an idler pulley 26 secured in hangers attached to the baseof the frame, and secured at the opposite end to the' end of alever 27fulcrumed upon the frame at 27 and extending beneath the key board, andprovided with a key. In this construction the revolution of the screwshaft to ad- Vance the carriage revolves pinion 24, gear 23, and barrel23' and winds strap 25 upon the barrel, so that when it is desired torevolve the shaft to return the carriage, the outer end of lever 27 isdepressed, causing a pull upon the strap, and a rapid revolution of thescrew-shaft through the multiplying gears 23 and 24.

In Figs. 7, 8, and 9 I have shown a modified form of mechanism forreturning the screwV shaft, Fig. 9 being a somewhat enlarged view. Inthis construction gear 23 is movable upon its shaft, but revolvestherewith being secured by a key and a key way. Upon the same shaft withgear 23 is secured a :ratchet wheel 23 and brake wheel 29, there being acoiled spring 30 secured at one end to a pin 3la projecting from theframe the opposite end being secured to the ratchet wheel, so that whenthe ratchet wheel is revolved the spring is put in tension. and brakewheel 29 are revolved by means of a pawl lever 31, and pawl 32, lever 31being connected with a lever 33 the outer end of the lever beingprovided with a cross bar 34 with which the key levers contact to causethe pawl to revolve ratchet wheel 23 one notch or the distance of oneratchet each time a character is printed, or a space formed. In order tohold the ratchet wheel against the tension of the spring, a pawl 35 ispivotally secured upon a bar 36 pivoted upon the frame in a manner toengage with the ratchet wheel and hold the same as advanced from returnmovement. By this arrangement the spring is put in tension as the screwshaft is advancing the carriage and being in slight tension initially,it is ready to return the carriageupon the release of the pawls 32 and35 and engagement of gears 23 and 24, whether the carriage has traveledthe distance to form but a character of a line, or the entire length. Inorder to engage the gear 23 with gear 24 and at the same time releasepawl 35, I at- Ratchet wheel 23 tach a spring 37 to a lug 38 upon theframe and curve the spring centrally perforating it at this point toallow the spring to receive the journal of wheel 23, and attach thespring to the wheel so that the outward normal tension of the springwill hold gear 23 out of mesh with pinion 24, the lower end of thespring being inclined away from the wheel and bent at an acute angle at39, there being a bar 40 bent at the upper end atan opposite angle toangle 39, so that as the bar is raised by depressing lever 4l to whichbar 40 is pivoted, the spring is forced in carrying the gear 23 with itand forcing it into mesh with pin ion 24. Bar 36'to which pawl 35 ispivoted is formed with an angular arm 42, the end of which is in a pathof travel of a pin 43, uponbar 40, and as the bar 40 is raised the pincontacts with arm 42 and trips the pawl (pawl 32 having normally droppedfrom contact with the ratchet wheel) thereby releasing the ratchetwheels, and allowing the spring to act upon the same causing gear 23 torevolve gear 24, and the screw shaft to return the carriage. Should thespring revolve the gears with too great rapidity, a further depressionof lever 4l will apply brake 44 secured to bar 40 by means of an angularhanger 45, and check the speed of rotation of the same. As each typelever is supplied with upper and lower case type and characters, thecarriage is moved forward to print the capitals, and this movement isaccomplished by revolving screw shafts 7 thron gh the medium of quadrantshaped rack bars 46 pivoted to the frame at 46', and meshing with mitergears 47 upon shafts 7, there being levers 48 connected with rack bars46 and operated by a key marked in the `drawings shift it beingunderstood that the two levers 48 are connected by a cross bar 4S' sothat the twolevers work in unison to revolve the quadrant rack bars toadvance the carriage support toward the operator, the levers beingraised to return the carriage by means of a spring 50 secured at one endto the up per portion 3 of the frame and bearing at the free end uponthe lever, so that the carriage is advanced by rocking the quadrantrackbar, on depressing the key, and returned by the action of thespring, as it returns the levers to their normal horizontal position,and in the act rocks the quadrant rack bar to reverse the direction ofrotation of the screw shafts 7.

5l designates the platen, revolubly journaled upon the carriage, andprovided with a wheel 52 at the right hand side of the machine, by whchto turn the same manually, the opposite end being formed with a circularratchet face 53 by which to automatically revolve the platen through themedium of a mutilated gear 54 journaled upon the carriage and meshingwith a gear 55, also jonrnaled upon the carriage and provided with apawl 5G which engages with the ratchet face 53 of the platen.

Gear 54 is formed with a depending' tooth IOO tog:

l54 having an inclined side adapted to ride over a catch 57 pivoted atthe left hand side of the frame and allowed to swing outwardlysufficient to allow the .tooth to pass the same but prevented fromswinging inwardly by a stop 57 so that as the carriage is returned,tooth 54 will ride over catch 57 and engage the same, andas the carriagemoves to the right the gear 54 will be given a partial turncommunicating a like motion to gear 55 and pawl 56, which gives to theplaten a rotary lnovement sufficient to space a line, the spring 58returning gears 54 and 55 to their original position.

In order to notify the operator of the near approach to the end of themovement of the carriage, I have provided for a plurality of alarms bymeans of a catch 59pivoted tothe carriage support and allowed to swingout of the way when the carriage is being returned, but prevented fromswinging in an opposite direction by means of a stop 59.

60 designates a lever fulcrumed centrally vand formed with a pluralityof notches 60 at .one end and a hammer at the opposite end adapted whenthe lever is depressed at the end upon which the notches are formed byriding over the catch, and allowed to rise by reason of the notches tosound an alarm by reason of the hammer striking a gong61, the alarmbeing sounded once for each notch, and again as the lever passes thecatch finally, causingthre alarms if the carriage is moved to cause thelever to fully passthe catch the free swinging movement of the catchtoward the left hand kside ot' the machine allowing the return of thecarriage as the catch swings freely when the lever contacts therewith.

62 designates Ya guide for the paper comprising arms to which is secureda rod 63 by which to align the paper there being a guidev 64 upon therear side of the platen.

I provide for a continuous wind of the ribbon in either direction bymeans of revoluble shafts upon the outer ends of each of which issecured wheels 65, having four projecting pins, with which the hook endsof bar 66 engage, the bars being hooked upon each side of their upperends, and secured at their lower ends to a lever 67 operated by the keylevers as the opposite end of cross bar 17 attached to lever l5` issecured to the end of this lever by which means a synchronous movementis given to bars 14 and 66, and the ribbon is advanced and revolvedfromone spool 70 to the spool 70 upon the shaft upon the opposite sideof the platen. The bar 66 is held in engagement with the pin of wheel bymeans of a spring 66 as shown in Fig. 5. When the ribbon has been woundfrom one spool to the other, bars 66 are shifted from one side of thepin-wheels to the opposite side to give a reverse movement to thespools. In order to shift the ribbon laterally to present a new surfaceto the type the spools are movable upon their shafts as shown in Fig.10, and are held in adjustment by means of a spring dog 7l which engagesnotches' formed in the key which key prevents the spool from rotatingupon the shaft.

72 designates an ordinary friction roller, for insuring a propermovement of the paper.

The type bars comprise each asingle rod or wire with a. horizontalportion 73, journaled in grooves formed in semi-circular boards 74having top plates 75 of semi-circular contiguration, and formed withco-incident grooves so that the rods are closely confined but preventedfrom other than rotative movement. The rear ends 76 of the type bars arebent vertically downward from the horizontal portions, and are providedwith the type and type characters usually employed in type writing bothin small and capital letters, the capitals being arranged above thesmall letters. The opposite ends 77 of the type bars are benthorizontally at right angles to the horizontal portions and areconnected with the key levers, which are right angled levers thehorizontal portions 78 of which are fulcrumed upon a rod 79 and thevertical portion 80, connected with the type bar so that by depressing akey 8l the vertical portion 8O of the key lever rocks the horizontalportion of the type bar, and raises the end 7 6 to cause the same tocontact with the ribbon and print the character. to regulate themovements ofthe key levers to cause each character to impact with theribbon ,with the desired force, and to prevent an excessive impact, abar 82 is arranged across the machine above the horizontal portionsof Inorder thelevers and provided with set screws 83,

one for each lever, and directly over each lever, whereby the nestadjustment may be madevto the movement of each lever.

In order` to assemble the type bars within the smallest area, and tocause the type` to strike at the proper point, in perfect alignment, thehorizontal portions 73 are arranged at such an obtuse angle to theimpact point of the type as will bring the type to a common point wheneleva-ted.

In order-to clean the type mechanically, I provide a brush 84 ot'semi-circular form and secure the same to a swinging frame 85, whichnormally rests below the type, and arrangea lever 86 which whendepressed at one end raises the brush and causes the same to retog1 IIO

movevany foreign substance from the type that may be thereon. The keysare formed with a horizontal portion with which the [ingers contact, anda vertically inclined portion 88 immediately in front of theoperator,and designed to receive the character to in dicate the particular key tobe depressed, this arrangement being of great value as it presents thecharacter in proper position to be more readily observed, than whenplaced upon the top ofthe key.

In operation, the carriage being at .the extreme movement to the leftofv the machine, and the paper properly arranged upon the platen, theoperator depresses the keys in the act of writing, which depresses theouter ends of levers 15 and 67, revolving the screw shaft 11 by lever 15and the action of,bar 14 upon wheel 12, and revolving the ribbon spoolsby the action of lever 67 and bars 66, until the carriage has advancedto its limit, the alarm being sounded in the meantime by levercontacting with catch 59, when the carriage is returned either bydepressing lever 27 and pulling upon strap 25, or by depressing lever 41and releasing the pawl to allow spring 30 to act. When carriage hasreturned the full limit of its return movement tooth 54 is in engagementwith catch 57 when upon the forward movement of the carriage thegears54e and 55 are given a sufficient turn to cause pawl 56 to turn theplaten the distance to space a line.

If it is desired to use capitals, levers 4S are depressed causing thequadrant rack bar to revolve shaft 7 and advance the carriage supportand carriage.
